COLIC (from the Gr. K6Aov or KwAov, the large See also:intestine)  , a See also:term in See also:medicine of very indefinite meaning, used by physicians outside See also:England for any paroxysmal abdominal See also:pain, but generally limited in England to a sudden See also:sharp pain having its origin in the See also:pelvis of the See also:kidney, the ureter, See also:gall-See also:bladder, bile-ducts or See also:intestine . Thus it is customary to speak of renal, biliary or intestinal See also:colic . There is a growing tendency, however, among professional men of to-See also:day, to restrict the use of the word to a pain produced by the contraction of the See also:muscular walls of any of the hollow viscera of which the See also:aperture has become more or less occluded, temporarily or otherwise . For renal and biliary colic, see the articles KIDNEY DISEASES and See also:LIVER, only intestinal colic being treated in this See also:place . In infants, usually those who are " See also:bottle-fed," colic is exceedingly See also:common, and is shown by the See also:drawing up of their legs, their restlessness and their continuous cries . Among adults one of the most serious causes is that due to See also:lead-poisoning and known as lead colic (Syn. painters' colic, colica Pictonum, See also:Devonshire colic), from its having been clearly ascertained to be due to the absorption of lead into the See also:system (see LEAD-POISONING) . This disease had been observed and described See also:long before its cause was discovered . Its occurrence in an epidemic See also:form among the inhabitants of See also:Poitou was re-corded by See also:Francois Citois (1572–1652) in 1617, under the See also:title of Novus et popularis apud Pictones dolor colicus biliosus . The disease was thereafter termed colica Pictonum . It was supposed to be due to the acidity of the native wines, but it was afterwards found to depend on lead contained in them . A similar epidemic See also:broke out in certain parts of See also:Germany in the end of the 17th See also:century, and was at the See also:time believed by various physicians to be caused by the admixture of See also:acid wines with litharge to sweeten them . About the See also:middle of the 18th century this disease, which had long been known to prevail in Devonshire, was carefully investigated by See also:Sir See also:George See also:Baker (1722–1809), who succeeded in tracing it unmistakably to the contamination of the native beverage, See also:cider, with lead, either accidentally from the leadwork of the vats and other apparatus for preparing the liquor, or from its being sweetened with litharge .

In Germany a similar colic resulting from the absorption of See also:

copper occurs, but it is almost unknown in England . The simplest form of colic is that arising from habitual See also:constipation, the muscular See also:wall of the' intestines contracting painfully to overcome the resistance of hardened scybalous masses of faeces, which cause more or less obstruction to the onward passage of the intestinal contents . Another equally common cause is that due to irritating or indigestible See also:food such as apples, See also:pears or nuts, heavy pastry, See also:meat pies and puddings, &c . It may then be associated with either constipation or See also:diarrhoea, though the latter is the more common . It may result from any form of See also:enteritis as See also:simple, mucous and ulcerative colitis, or an intestinal See also:malignant growth . The presence of ascaris lumbricoides may, by reflex See also:action, set up a very painful See also:nervous spasm; and certain forms of See also:influenza (q.v.) are ushered in by colic of a very pronounced type . Many physicians describe a rheumatic colic due to See also:cold and See also:damp, and among See also:women disease of the pelvic See also:organs may give rise to an exactly similar pain . There are also those forms of colic which must be classed as functional or neuralgic, though this view of the See also:case must never be accepted until every other possible cause is found to be untenable . From this See also:short See also:account of a few of the commoner causes of the trouble, it will be clear that colic is merely a symptom of disease, not a disease in itself, and that no diagnosis has been made until the cause of the pain has been determined . Intestinal colic is paroxysmal, usually both beginning and ending suddenly . The pain is generally referred to the neighbourhood of the umbilicus, and may radiate all over the See also:abdomen . It varies in intensity from a slight momentary discomfort to a pain so severe as to cause the patient to shriek or even to break out into a cold clammy sweat .

It is usually relieved by pressure, and this point is one which See also:

aids in the See also:differential diagnosis between a simple colic and See also:peritonitis, the pain of the latter being increased by pressure . But should the colic be due to a malignant growth, or should the intestines be distended with See also:gas, pressure will probably increase the pain . The temperature is usually subnormal, but may be slightly raised, and the See also:pulse is in proportion . In the treatment of simple colic the patient must be confined to See also:bed, hot fomentations applied to the abdomen and a purge administered, a few drops of See also:laudanum being added when the pain is exceptionally severe . But the whole difficulty lies in making the differential diagnosis . Acute intestinal obstruction (ileus) begins just as an attack of simple colic, but the rapid increase of illness, frequent vomiting, anxious countenance, and still more the See also:condition of the pulse, warn a trained observer of the far more serious See also:state . See also:Appendicitis and peritonitis, as also the gastric crises of locomotor ataxy, must all be excluded .
